Decathlon has good deals on clothing and helmets as well as other gear.
Bikes Direct has great deals on all kinds of bikes at different budgets. I’ve never ridden any but reviews are good and I probably will get a bike from them someday.
11 Speed Entry Level Bike from Bikes Online
Bikes online also seems like a great resource. The bike listed in this link is a type I’d recommend for someone’s first road bike. I haven't ridden this specific bike but a bike with Shimano 105 11 speed that is about $1,000 is ideal in my opinion. More soon on how to pick your first road bike!
The Black Bibs
The Black bibs is a great resource and has all types of cycling clothing as well as one of the best deals on bibs and shorts.
If you want to go down the Ali Express Rabbit Hole Trace Velo is an excellent guide! It is a bit of a crap shoot but I have made some sweet scores from this site for sure!
This is Just the Beginning to help you get started more soon!
